E-Waste graveyardLarge trucks bring containers of hard drives, monitors, servers and other hi-tech cast-offs. Workers break them up, salvage what they can sell and leave the rest on the streets for others to pick through. A crackdown by the Chinese authorities earlier this year closed some of the workshops. I posed as a student to visit the remaining ones. Some owners were very aggressive – others invited me in for tea. These workers are sorting plastic by heating it with a cigarette lighter and sniffing the fumes. They complained of headaches.
